Hi all..

I have a Sun Ultra 450 with a lot of drives and scsi controllers installed and i have one bad internal disk.. How can "map" ex /dev/dsk/c3t2d0s0 to a slot in the internal cabinet? Any good ideas?

I dont want to remove the wrong disk

thanks in advance..

You could very easily take out the wrong drive. When building out an E450 and adding
the extra controllers, the cables go from the (looking from the front of the
system) right to left/rear. It is not murphy-proof in that you could end up putting
the wrong cable in the wrong slot at the back. If that happens, then your controllers
are set up differently.
You can easily see how you could get screwed up here. The format command shows disks
but may throw you off since the cables could be wrong.

If drive c3t2 (number 10 in this list) was bad, then you should take the
drive out of slot 10. If your cables are crossed, then it would be
slot 18. If you come across an E450 like this, then note the problem
on the server (physically by printing the "incorrect layout" and tape it on
the server) so you will know in the future.

Your best bet - run format and copy the output and print it. Find the
drive you believe is bad (you have the controller number (c3t2),
shutdown and run probe-scsi-all. Then pop out the 'bad' drive
and run it again. If the "/pci@6,4000/scsi@3,1/sd@2,0" doesn't show up (the
name of slot 10 from format command, you got the correct one. If it's still there,
then look for which one was removed. You should be able to see that your
cables must be crossed.

And here are some SunSolve Docs that might help....
